Conformational, configurational, and supramolecular studies of podocephalol acetate from Lasianthaea aurea

Although podocephalol ( 1 ) and its derived acetate 2 were found in Lasianthaea podocephala four decades ago, and 1 was later detected in the essential oils of several vegetal species, its absolute configuration (AC) and conformational preferences remained to be established. The structures of ar ‐himachalene 1 , now isolated from Lasianthaea aurea , and its derived acetate 2 , were herein confirmed by extensive 1D and 2D nuclear magnetic...
